In ROCH, Gwok Jing faced mortal danger against the Golden Wheel Monk, Wan Hak Sai, Siu Seung Tze, Lui Mor Singh, and Ma Gorn Jor (yeah...not really, but still...). In DGSD, Kiu Fung nearly succumbed to 200+ wulin warriors at Tsui Yin Manor.
Gwok Jing's opponents included a Greats-level fighter and three experts who, individually, seemed more powerful than any one of the two-hundred or so warriors who ganged up on Kiu Fung at Tsui Yin Manor. On the other hand, it's fighting four or five compared to fighting *two-hundred*. Which of the two great wuxia heroes was in greater peril?
